CC   -!- FUNCTION: Part of ribonuclease P, a protein complex that generates
CC       mature tRNA molecules by cleaving their 5'-ends. {ECO:0000255|HAMAP-
CC       Rule:MF_00757}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage of RNA, removing 5'-extranucleotides
CC         from tRNA precursor.; EC=3.1.26.5; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00757};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00757};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00757};
CC   -!- SUBUNIT: Consists of a catalytic RNA component and at least 4-5 protein
CC       subunits. {ECO:0000255|HAMAP-Rule:MF_00757}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00757}.
CC   -!- SIMILARITY: Belongs to the eukaryotic/archaeal RNase P protein
CC       component 4 family. {ECO:0000255|HAMAP-Rule:MF_00757}.
